2014 Audi A6 2.0L Diesel · OO08 PRL

The 2014 Audi A6 failed its most recent MOT on 2024-03-18, with three major faults—insufficient front windscreen washer liquid, an electronic stability control (ESC) fault, and a malfunctioning electronic parking brake system—alongside minor and advisory issues. This failure marks a significant deviation from the vehicle’s previous MOT history, which predominantly showed either clean passes or minor, non-major defects, particularly concerning the rear position lamps. The recurring nature of the ESC and parking brake advisories suggests underlying electrical or control module issues that may require professional diagnosis, as these faults are not easily rectifiable through basic maintenance. The presence of a TPMS (Tyre Pressure Monitoring System) light on the vehicle indicates a potential sensor failure or low tyre pressure, which, if unresolved, could lead to further tyre damage or safety concerns. The recorded mileage of 102,747 miles for a vehicle aged approximately 12 years represents an annual usage rate of around 8,562 miles, which is within the expected range for a car of this age and class. However, the mileage alone does not fully explain the vehicle’s condition, as periods of inactivity can exacerbate issues such as standing corrosion, particularly in the brake systems and undercarriage. The absence of significantly higher mileage accumulation suggests that the vehicle may have been driven moderately, but this does not negate the need for thorough inspection, especially given the recent MOT failures. The wear patterns observed, such as uneven tyre wear and visible tyre damage, point to potential alignment or suspension issues that have not been fully addressed. Given the recent MOT failures and recurring advisories, the prospective buyer should prioritise a comprehensive inspection of the vehicle’s electrical systems, specifically the ESC module, parking brake actuator, and TPMS sensors, as these are critical for road safety. On a test drive, listen for unusual electrical whining or grinding noises from the ESC system, which could indicate failing sensors or wiring harnesses. The electronic parking brake system should be tested by engaging it manually to confirm it operates independently of the vehicle’s electrical system; if it binds or fails to release, this may require a replacement actuator or wiring repair. The tyre damage observed in 2022-08-16—particularly the front tyres with structural tears—is a severe concern and warrants immediate replacement, as these defects compromise tyre integrity and pose a safety risk. Additionally, check for any oil misting in the rear suspension bushes, which, if left untreated, can lead to further suspension failure and reduced handling stability. For the buyer, the vehicle’s age and the presence of tyre damage and electrical faults mean that immediate action is necessary. Beyond the MOT failures, the uneven rear tyre wear from 2020-08-12 suggests that the suspension alignment may have been neglected, leading to uneven loading across the tyres. This could also contribute to accelerated wear on the suspension components, such as the shock absorbers, which were noted to have light oil misting in previous MOTs. It is advisable to replace the front tyres immediately, as the structural tears are not only illegal but also highly dangerous. The rear suspension advisories should be addressed to prevent further oil leakage, which could lead to degraded suspension performance and potential failure. For the electrical systems, a thorough diagnostic check by a qualified mechanic is essential to identify and rectify the ESC and parking brake faults, as these issues could recur without professional intervention. In the interim, ensure that the windscreen washer system is topped up with a suitable fluid to prevent further washer liquid issues.
